【摘要】 运用ANSYS有限元分析软件对一双塔楼连体结构和单体结构进行了对比分析。通过建立三维计算模型,比较了两种结构的动力特性,并采用反应谱法和时程分析法对两种结构施加x、y向水平地震激励,得出了两个方向地震作用下的两种结构的底部剪力时程曲线、顶层位移时程曲线和加速度时程曲线.以及层位移变化曲线。计算结果表明,双塔连体结构由于增设了连体,可以很好的协调两个塔楼的运动与变形,使得整个结构的受力与变形与单体结构类似,具有良好的抗震性能。更多还原

【Abstract】 A double-tower connecting tall building which stands in vivid contrast against a mono-building is analysised by ANSYS finite element program, by which builds a three-dimension calculating model in this paper. By comparing the dynamic characteristics of a double-tower connecting tall building with a mono-building, the results illustrate the differences of them. The spectrum analysis and the time history dynamic analysis of the two types of buildings are carried out in x and y direction,and the time-dependent curve of bottom shear,roof horizontal displacement and acceleration are achieved, Floors displacement curve is also achieved. These results demonstrate that the connecting unit of the double-tower connecting tall building can make the movement and deformation of two towers harmonized,and the whole framework will performance like the mono-building with good aseismatic capability.更多还原
